😴 Sleep function in Go - pause the program execution

To pause the execution of a current program in Go, delay code execution, and wait for a specified period of time, you just need to use the Sleep() function defined in the time package. As an argument, this function takes a variable of type time.Duration, which is the amount of time the program execution should be stopped for. It can be expressed as a number multiplied by a unit constant. For example 3*time.Second means that the execution will be stopped for 3 seconds. Available units are:

• time.Nanosecond
• time.Microsecond
• time.Millisecond
• time.Second
• time.Minute
• time.Hour

package main

import (
    "fmt"
    "time"
)

func main() {
    fmt.Println("before Sleep()")

    time.Sleep(3 * time.Second)

    fmt.Println("waking up after Sleep()")
}
